>10. The WOW! signal
There are numerous explainations, but most of them are useless until we see it happen again. Without repeated observations, we aren't able to do much with it. For all we know, it could've just been an illegal transmission bouncing off space debris or even just a recording malfunction. Rare, seemingly unique astronomical events don't get explained overnight, you know.
>9. Pioneer's Funky Voyage
Again, something that we just haven't had enough time or data points to do anything meaningful with yet. New Horizons will hopefully help us out.
>8. Female Orgasms
This one is just plain retarded. There isn't really anything TO explain. Saying that there MUST be a purpose to it is just plain stupid. Biology doesn't work that way. You can hypothesize about how it came about all you want, but in the end it's all meaningless because there's no way to prove anything yet. It's the same deal as all these "what's the evolutionary advantage of..." threads (sorry, I'm not here often, so I don't know if it's a meme now or not).
>7. Dark Energy
A strawman. We can only not explain Dark Energy if it actually exists. Dark Energy is only a placeholder for holes in one model, but there are plenty of other hypotheses to explain the observations.
>6. The Speed of Light
>According to Einstein’s theory of relativity, it is impossible to exceed the speed of light.
Yet another strawman. That's not what the theory says at all. What it says is that nothing with mass can accelerate to localized lightspeed. There are things like tachyons that (in theory) travel faster than light (though they have their own issues, like existing in imaginary (sqrt(-1)) time).
Anyway, no individual particle or energy wave in the experiment is actually moving faster than lightspeed.

>5. The Placebo Effect
The Placebo Effect is actually fairly well understood, considering how very very very little we know about the hideously complex interactions of the human brain. Numerous chemical reactions triggered by emotions and such as well as specific brain functions and regions have been linked to placebo responses. It basically boils down to the fact that the brain and consciousness have a LOT more control over body functions and health (or percieved health) than we previously thought. We know a lot about how very specific small scale things happen, but we just plain haven't had enough time to unravel the mysteries of the brain to say how it all fits together.
>4. Cold Fusion
The initial controversies surrounding cold fusion (read the wikipedia article for details) caused a serious mistrust of the whole subject and resulted in a severe lack of funding. If it exists at all, the only reason we don't understand it is because we haven't really given it a chance. More of a fault with politics than with Science.
>3. Yawning
See #8. There doesn't have to BE a singular or even GOOD reason. That's not how nature fucking works.
>2. Dark Matter
See #7. Can you tell I'm bored of this retarded bullshit?
>1. What Came Before, What Will Come After
We CAN explain what came before the Universe and what it's likely fate is. See: Big Bounce and Heat Death. Observations and changes in our laws of Physics may require abondoning these hypotheses, but we do have explainations. The other shit is Philosophy, not Science.
I guess my main theme here is that Science requires lots of time and effort. Saying "oh, look at all these things you can't explain" isn't fair because the more we know, the more questions there are. Science is a process, not an Answer. But still, that only applies to numbers 10, 9, 5, 4, and maybe the main point of 1. The rest are strawmen, blatent ignorance and misinformation.
